【摘要】 在太湖流域西部的太湖与滆湖间的区域内,选择了25个监测点,对6种典型水体中TN,TP及COD含量进行了为期1年的动态监测。结果表明,6种水体枯水期TN,TP平均含量都远高于丰水期和平水期含量,枯水期TN含量较高的水体为湖水、入湖河流及畜禽养殖厂周围水体,TP含量较高的水体为居民生活区及畜禽养殖厂周围水体。各水文期不同水体COD平均含量排序为:枯水期COD含量较高的水体为水产养殖场及居民生活区周围水体;丰水期COD含量较高的水体为湖水和农田及居民生活区周围水体;平水期COD含量较高的水体为水产养殖场周围水体。更多还原

【Abstract】 This paper dealed with 25 monitoring station , monitored the contents of TN,TP and COD in 6 kinds of water body on the west of Taihu valley between Taihu lake and Gehu lake, which lasted for one year. The result showed that the average contents of TN and TP in 6 kinds of water body in low water season were higher apparently than that in high and normal water season. In low water season, the contents of TN of the water in Taihu lake, the water in the river that arrive to Taihu lake and that around the livestock and poultry breeding plant were higher than that in the other water body, and the contents of TP of the water around residential area and livestock and poultry breeding plant were higher than that in the other water body. In low water season, the water body, which contents of COD were higher than the others, were the water around aquiculture site and residential area; in high water season, that were the water in Taihu lake, the water around cropland and residential area;and in normal water season, that was the water around aquiculture site.更多还原
